Definitions

  • the invention relates to a weaving rotor for pneumatic row shed looms, each with a weft warp leading weft insertion lamella combs.
  • the invention has for its object to provide a weaving rotor of the type defined, which has the necessary control means and is very simple in construction, so that the control means are largely maintenance-free.
  • a weaving rotor 1 with one end 2 is fixedly connected to a stub shaft 3 and is freely rotatably supported on a stub shaft 5 with the other end 4.
  • the stub shaft 3 is driven by the main shaft of the loom, the stub shaft 5 is fixed.
  • Within the weaving rotor 1 there is a fixed switching tube 7, lying against the inner wall 6 with little play.
  • One end 8 of the switching tube rests freely rotatably on the shaft end 3.
  • a tube 9 runs through the fixed shaft end 5 and is connected to a compressed air source is and opens into an interior 10 of the switching tube 7.
  • the other end 11 of the switching tube 7 is clamped on this tube 9 by means of a clamping ring 12, so that the switching tube cannot rotate.
  • the weaving rotor 1 carries on its circumference 15 a number of weft insertion lamella combs 16 which extend in the longitudinal direction and which alternate in the circumferential direction with an equal number of stop lamella combs. Only one entry comb 16 is drawn, the stop combs are not shown.
  • Each entry comb 16 has its length, i.e. Distributed over the weaving width of the weaving rotor, a number of relay nozzles 17, which in turn convey a weft thread through the insertion channel in the comb.
  • the weaving rotor 1 contains a radial wall bore 18 which is connected to the air supply channel 19 of the associated relay nozzle.
  • the wall bores 18 of an entry comb lie on a surface line 20.
  • the switching tube 7 has as many slots 21 which lie on an elongated helical line 22 which runs on the circumference of the switching tube 7 and is offset in the direction of rotation with respect to the surface line 20.
  • Each slot 21 is aligned in the circumferential direction with a wall hole 18 in the weaving rotor 1.
  • the length 1 of the slots is determined by the weft insertion process of the weaving machine. If the chain spans the weaving rotor over an angle of 120 °, a weft thread must be fully inserted in the period in which the weaving rotor has rotated through 120 °, i.e. its tip must have covered the full width of the weave.
  • the relay nozzles of the entry comb in question are to be fed with compressed air from the switching tube in accordance with the advancing thread tip in an entry channel.
  • the length 1 of the slots 21 in the switching tube is adapted to the required blowing time of the relay nozzles.
  • the distance y in the circumferential direction with respect to a wall bore 18 in the weaving rotor of each slot is determined by the location which a weft thread tip has reached at the instantaneous angle of rotation at a given thread speed.
  • the interior of the switching tube is kept constantly filled with compressed air.
  • the wall bores 18 move one after the other, starting with the wall bore 18 'and ending with the wall bore 18 "from left to right via the stationary slots 21' to 21" of the switching tube 7, so that in each case a flow connection for the compressed air is established between the switching tube and the air supply duct 19 in the respective relay nozzle.
  • the relay nozzle blows on the weft thread and conveys it further through the entry channel 23 of the entry comb.
  • the flow connection is interrupted and the associated relay nozzle no longer blows.
  • the slots are arranged in the circumferential direction of the weaving rotor in such a way that several successive relay nozzles blow simultaneously for each weft thread in an insertion channel; in this example there are about eight nozzles.
  • round bores 25 are additionally provided in the switching tube 7.
  • the bores 25 are aligned with the slots 21 in the circumferential direction. They lie on a surface line 26, specifically where the entry has ended, that is to say after the weaving rotor has completed a rotation of 120 °. Since the bores 25 are constantly moving closer to the slots 21 in the entry direction, they together form a longer slot 27 towards the end of the weaving rotor. After the rotation through 120 ° has ended, the weaving machine must also be stopped in the event of weaving errors.
  • a bore 25 can be assigned to every second bore 18.
  • the tube 9 can be fastened to the machine 29 by means of a clamping ring 30. After loosening a screw 31 in the clamping ring 30, the tube 9 can be rotated so that the switching tube 7 connected thereto can be rotated with respect to the weaving rotor 1 and the start and end of the blowing times of the relay nozzles 17 can be set.
